This review focuses on the application of process engineering in electrochemical energy conversion and storage devices innovation. For polymer electrolyte based devices, it highlights that a strategic simple switch from proton exchange membranes(PEMs) to hydroxide exchange membranes(HEMs) may lead to a new-generation of affordable electrochemical energy devices including fuel cells, electrolyzers, and solar hydrogen generators. For lithium-ion batteries, a series of advancements in design and chemistry are required for electric vehicle and energy storage applications. Manufacturing process development and optimization of the LiF eP O_4/C cathode materials and several emerging novel anode materials are also discussed using the authors' work as examples.Design and manufacturing process of lithium-ion battery electrodes are introduced in detail, and modeling and optimization of large-scale lithium-ion batteries are also presented. Electrochemical energy materials and device innovations can be further prompted by better understanding of the fundamental transport phenomena involved in unit operations. 展开更多

Three-dimensional(3D)covalent organic frameworks(COFs)are crystalline porous polymers with potential in numerous high-tech applications,but the linkages involved in their synthesis are still rather limited.Herein,we report novel 3D sp^(2) carbon-linked COFs fabricated by the formation reaction of C=C bonds and their application in fluorescence imaging.These new COFs,namely JUC-580 and JUC-581,show high stability and excellent light-emitting properties in solid state and dispersed in various solvents.Furthermore,we investigate the potential application of JUC-581 as a drug carrier combined with fluorescence imaging.These results indicate that 3D sp^(2) carbon-linked COFs are not only potential drug-loaded and sustained release materials but also promising cell fluorescent stains.This study thus expands the structural categories of 3D COFs based on different linkages,and promotes their prospective applications for biomedicine and fluorescent materials. 展开更多
